Which radars cover Royalton?
The closest NEXRAD Doppler radar is KPAH (Paducah, KY), about 59 miles south-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Royalton | View |
|---|---|---|---|
| KPAH Paducah, KY | 59 mi south-southeast | 4,500 ft | Good — most storms and steady rain or snow show clearly |
| KVWX Evansville, IN | 80 mi east-northeast | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 102 mi northwest | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
